Problems solved by technology
The existing method for determining the location of ground anchor pits requires at least two operators, and the measurement takes a long time. Due to the influence of the flatness of the ground on the job site and the shelter of equipment and materials, the existing measuring tools, usually meter sticks, cannot be used at all. Accurately determine the distance and orientation of the ground anchor pit, which cannot meet the standard requirements of the derrick ground anchor pit

Embodiment 1
[0029] In order to overcome the existing use of meter ruler measurement to determine the location of the ground anchor pit, the measurement takes a long time and is affected by the flatness of the ground on the job site and the shelter of equipment and materials. It is impossible to accurately determine the distance and orientation of the ground anchor pit, and the derrick cannot be reached The problem that the code standard requirement of ground anchor hole, the present invention provides such as figure 1 The derrick ground anchor hole positioning device and positioning method shown in the present invention only need to be operated by a single person and a single machine by adopting micro-motor drive, gyro calibration, and laser ranging positioning. The equipment is simple, easy to operate, and convenient to use. The labor intensity of on-site engineering and technical personnel is reduced, and the precise positioning of the position of the anchor pit of the derrick is realize...

The invention relates to a derrick ground anchor pit positioning device and method, and belongs to the technical field of oil and gas field downhole operation. A derrick ground anchor pit positioningdevice comprises a controller, a cable, a measuring platform, a second micro motor, a third micro motor, a supporting leg frame, a center shaft rod and a movable platform. The measuring platform comprises a laser emitter, a gyroscope and a first micro motor. The controller is connected with the first micro motor, the second micro motor and the third micro motor through the cables, and the measuring platform accurately adjusts and positions the ground anchor pit through an angle instruction and a distance instruction input by the controller. The device is simple, easy to operate, convenient touse and capable of being widely applied to accurate positioning of the derrick ground anchor pit in the petroleum field.
Description
technical field [0001] The invention belongs to the technical field of downhole operations in oil and gas fields, and in particular relates to a derrick anchor pit positioning device and a positioning method. Background technique [0002] In the process of oil exploration and development, drilling, workover, oil testing and other operations require the use of derricks. In order to prevent the derrick from tilting during the construction process and affect the safe operation of the wellhead, the derricks used on site are fixed by symmetrical steel wire ropes. One end of the wire rope is fixed on the top of the derrick, and the other end is fixed on the ground anchor. If the distribution of the anchor pits of the derrick is asymmetrical, the force on the steel wire ropes on the left and right sides will be uneven, and the derrick will tilt to the left or right during the construction process. The column eccentric wears the sealer, which makes it impossible to trip normally, a...
